Serious Seeds - Who are we?

  • Serious Seeds is one of the longest established seed-companies in Holland, concentrating on the production of high-quality, stable and consistent varieties of cannabis seeds.
  • The production of top quality cannabis-strains for medical and recreational purposes are our highest priority.
  • Independent and reliable lab tests (over 20 years of experience in this field) have shown that the different Serious Seeds strains produce the strongest plants (highest in THC-content) available on the market today, averaging between 18-22% THC.
  • These tests were done on plants grown from the same seeds as the customer receives.
  • For most of our strains, stable plants are crossed to produce the vigorous F1-hybrids that we sell.
  • You can be assured of good germination and uniform plants, we even guarantee the germination of our seeds.
  • Serious Seeds are produced in small numbers and are always fresh and hand selected. We test every batch of seeds for germination rate and uniformity of the resulting plants before releasing it.
  • We are the ONLY company to individually number our packages, so every seed can be followed from production to the point-of-sale in the shop.
  • KEEP THE ORIGINAL PACKAGE WITH THE INDIVIDUAL NUMBER ON IT after you buy the seeds, if any quality-problems occur and we can identify the pack as an original Serious Seeds pack, we will send you a new package for FREE!
